FRUITING POTENTIAL AND FLOWER TRUSS CHARACTERISTICS OF SELECT 'WILLAMETTE' RED RASPBERRY CANES |

| Abstract:
Fruits were hand harvested from canes of 'Willamette' red raspberries (Rubus idaeus) from June 18, through July 6, 1979. The fruiting canes had been pruned at 1.8 m and trained by weaving on a horizontal double wire trellis 1.4 m from ground line. Ten canes, to be studied for a distribution census of fruiting sites, were chosen at random from each of the 4.5 m experimental plots. Data relating to (1) number of fruits on each lateral branch, (2) the number of lateral branches in each 30.5 cm section, and (3) the number of berries with arrested development were collected. These data were correlated with yield. Most of the fruiting sites (55%) occured in the upper one-third cane. The upper one-half had 78% of the fruiting sites. Number of lateral branches and number of fruiting sites were closely correlated with yield. There was a negative linear correlation between yield and number of canes per plot. | |
